Duchess Horse Sanctuary Near Oakland, Oregon

It's a sanctuary for horses that have been abused, neglected, and used in the pharmaceutical industry. Pregnant mare urine is used to make Premarin and similar estrogen medications. Draft horses are used because they are bigger and produce more urine. The mares are kept pregnant and confined in stalls for years and then disposed of when they are no longer useful. A small fraction are rescued and allowed to live out their lives in comfort.
